Seachem salt will often cause inaccurate kh readings because of the high levels of borate. Most test kits read the combined total of borate hardness and carbonate hardness giving a higher reading than what the actually carbonate hardness is. When I used the seachem test kit and subtracted the borate I found that my actual carbonate hardness was about 2 dkh lower. So your kh is probably a lot lower then your already low reading.
